When re-installing a used oxygen sensor, coat the threads with hot bolt paste. This paste must not come into contact with slots on oxygen sensor body.

During installation, all cable ties must be re-installed at the same location.

Wires of oxygen sensors must always be secured in the same position when installing so that contact with the exhaust pipe is avoided.
